Circumstances:
The airline transport pilot was landing at the destination airport after a cross-country flight in visual meteorological conditions. The tower controller stated that the airplane's landing gear appeared to be extended during final approach and that the airplane landed within the runway's touchdown zone. The tower controller stated that, although the airplane made a normal landing, he heard a squealing noise that continued longer than what he believed was typical. The pilot subsequently transmitted "go-around." The tower controller acknowledged the go-around and cleared the pilot to enter a left traffic pattern. The tower controller stated that he heard the engine speed accelerate while the airplane maintained a level attitude over the runway until it passed midfield. He then saw the airplane pitch up and enter a climbing left turn. The tower controller stated that the airplane appeared to enter an aerodynamic stall before it descended into terrain in a left-wing-down attitude. Another witness reported that he saw the airplane, with its landing gear extended, in a steep left turn before it descended rapidly into terrain. A postaccident examination did not reveal any evidence of flight control, landing gear, or engine malfunction. An examination of the runway revealed numerous propeller slash marks that began about 215 ft past the runway's touchdown zone; however, there was no evidence that any portion of the airframe had impacted the runway during the landing. Additionally, measurement of the landing gear actuators confirmed that all three landing gear were fully extended at the accident site. Therefore, the pilot likely did not adequately control the airplane's pitch during the landing, which allowed the propeller to contact the runway. Due to the propeller strikes, the propeller was likely damaged and unable to provide adequate thrust during the go-around. Further, based on the witness accounts, the pilot likely did not maintain adequate airspeed during the climbing left turn, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall at a low altitude.
Probable cause:
The pilot's improper pitch control during the landing, which resulted in the propeller striking the runway, and his failure to maintain adequate airspeed during the subsequent go-around, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall at a low altitude.

Circumstances:
After takeoff from Milwaukee-Lawrence J. Timmerman Airport, while climbing, the pilot informed ATC about technical problems with the left engine and was cleared to return for an emergency landing. While trying to join the approach path, he lost control of the airplane that crashed in flames on a road located in Brookfield, about five miles southwest of the airport. The aircraft was destroyed by a post crash fire and all four occupants were killed.
Probable cause:
Engine failure or malfunction during climb to cruise. The following factors were reported:
- Powerplant failure due to fuel injection system obstructed,
- Foreign material affected normal operations,
- The pilot's attention diverted from operation of aircraft,
- The pilot failed to maintain flying speed,
- Low ceiling,
- N°1 cylinder nozzle core on left engine was partially blocked,
- Fuel flow 18 pounds per hour observed spinning.
